The Solicitors' Disciplinary Tribunal has recommended that solicitor Michael Lynn be struck off and that fines of €2 million should be imposed on him.
The tribunal found against Mr Lynn on more than 50 charges brought against him by the Law Society.
Tribunal chairman Frank Daly said Mr Lynn was "clearly someone who does not deserve to be a member of the legal profession".
He described the charges heard by the tribunal as a "series of serious offences", and said that Mr Lynn had caused hardship and distress to people trying to go about their business, and financial loss to people and institutions.
Mr Lynn was not present or represented at the hearing and the allegations were not rebutted, Mr Daly said.
